InfoDataFrame-class: Definition for S4 class InfoDataFrame

Description

InfoDataFrame has two slots: data and dimLabels.

Value

Class InfoDataFrame

Slots

data

A data.frame containing terms (rows) and measured variables (columns).

dimLabels

A character descripting labels for rows and columns.

Creation

An object of this class can be created via: new("InfoDataFrame", data, dimLabels)

Methods

Class-specific methods:

• dim(): retrieve the dimension in the object
• nrow(): retrieve number of rows in the object
• ncol(): retrieve number of columns in the object
• rowNames(): retrieve names of rows in the object
• colNames(): retrieve names of columns in the object
• dimLabels(): retrieve the slot 'dimLabels', containing labels used for display of rows and columns in the object
• Data(): retrieve the slot 'data' in the object

Standard generic methods:

• str(): compact display of the content in the object
• show(): abbreviated display of the object
• as(data.frame, "InfoDataFrame"): convert a data.frame to an object of class InfoDataFrame
• [i,j]: get the subset of the same class

Access

Ways to access information on this class:

• showClass("InfoDataFrame"): show the class definition
• showMethods(classes="InfoDataFrame"): show the method definition upon this class
• getSlots("InfoDataFrame"): get the name and class of each slot in this class
• slotNames("InfoDataFrame"): get the name of each slot in this class
• selectMethod(f, signature="InfoDataFrame"): retrieve the definition code for the method 'f' defined in this class
